5.5 Stator Head
The CAEMAX stator head provides noncontact energy supply of D
X
transmitters (SCTs) by
inductive coupling: An alternating magnetic field from the stator head induces voltage in the
secondary coil on the device. This induced voltage is used for supply of the D
X
transmitter
unit (SCT).

5.5.2 Installation and Placing into Operation

Mount the stator electronics at an arbitrary place next to the axle shaft.
Please note: Temperature rise of the stator electronics above 80°C may lead to
damage or even breakdown of the stator. To avoid that, provide sufficient heat
dissipation, e.g. by installing the stator on a metallic surface.

Install the secondary coil to the axle as described in section 6.5.2. The transmission
coil is to be installed directly below the stator.

Install the D
X
transmitter unit (SCT) to the axle and connect it. The connection strands
of the secondary coil have to be connected with the SCT inputs IP1 and IP2 (refer to
section 2.2).

Plug in the power cable of the ring stator and connect it to a 9 ...36 V DC power
source.
Please note: The DC connector of the D
X
RCI is not designed to supply a ring stator
or stator head while the RCI AC power supply is connected! A commercially available
plug-in power supply with at least 30 W power can be used for the power supply.

Wait for a couple of minutes. Check whether the D
X
SCT is sufficiently supplied with
power. To do this, measure the voltage between the EX- and EX+ outputs (e.g. the
power supply of the strain gauges). If the power supply of the D
X
SCT is sufficient,
you measure a voltage of 4.096 V DC.
